Abstract (en)

[origin: WO9936835A1] A toner usage estimation system is provided, in which an image file is analyzed to determine the relative usage of one or more toners used to define an image on a substrate. The image file is analyzed as a basis for estimating the cost of processing a particular print job. In one embodiment, a pixel coverage counter is added in the hardware path of a printer to count pixel coverage mapping, which allows the consumable usage of toner to be determined. In another embodiment, a software approximation on the coverage of toner is determined, based on the use of a reduced resolution thumbnail of an image.
